GLSA-200504-11 : JunkBuster: Multiple vulnerabilities

The remote Gentoo host is missing one or more security-related
patches.

Description :

The remote host is affected by the vulnerability described in GLSA-200504-11
(JunkBuster: Multiple vulnerabilities)

James Ranson reported a vulnerability when JunkBuster is configured to
run in single-threaded mode, an attacker can modify the referrer
setting by getting a victim to request a specially crafted URL
(CAN-2005-1108). Tavis Ormandy of the Gentoo Linux Security Audit Team
identified a heap corruption issue in the filtering of URLs
(CAN-2005-1109).

Impact :

If JunkBuster has been configured to run in single-threaded mode, an
attacker can disable or modify the filtering of Referrer: HTTP headers,
potentially compromising the privacy of users. The heap corruption
vulnerability could crash or disrupt the operation of the proxy,
potentially executing arbitrary code.
